ROTARY MOTOR.

Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed May 22, 1914. Serial No. 840,338.

To all whom it may concern Be it known that I, ELMER E. HAUnR, a citizenof the United States, residing at Springfield, in the county of Clarkand State of Ohio, have invented certain new and useful. Improvements inRotary M- tors, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to rotary motors and more particularly to a motorfor driving tube cleaners that is adapted to travel through a tube withthe cleaner, although it may be used for other purposes.

The object of my invention is to provide a simple and efficient motor ofgreat stability that will withstand the hard service of driving tubecleaning apparatus and with that end in view I form the main frame orbody with an outer and inner cylinder integrally with a supply head.This gives a rigid, stable and durable structure in which the parts arenot liable to jar loose.

With these and other objects in view my invention consists of theconstructions and combinations hereinafter described and set forth inthe claims.

In the accompanying drawings which form a part of this specificationFigure 1 is a longitudinal section of a motor embodying my invention.Figs. 2 and 8 are crosssections on the lines 22 and 83 respectively ofFig. 1 and Fig. 4 is a longitudinal section showing some modifications.

Like numerals represent the same parts in the. several views.

In the drawings 1 represents a supply head having forwardly projectingcylinders 2 and 3, the inner cylinder 8 having a crosspartition 4, saidhead, cylinders and partition being formed integrally as shown. Theinlet 5 of the supply head opens into the inner cylinder 3 and anopening 6 through the longitudinal wall of said cylinder admits themotive agent to an annular chamber 7 formed between the cylinders 2 and8. The inner cylinder 3 is shorter than the outer cylinder 2 and thebore of that portion of the outer cylinder which extends beyond theinner cylinder is enlarged forming a shoulder or inclined off-set 8. Aported partition 9 may be secured in any suitable way to form the frontwall of the annular chamber 7; but is shown as having inclined outerwalls seated against the offset 8 and tightened in place by beingscrewthreaded at 10 to the inner cylinder.

A rotary motor member 11 which is shown in the form of a turbine havingbuckets 12 operates within the motor chamber 13 formed by the enlargedforward portion of the outer cylinder 2 in front of the portedpartition, the motive agent being supplied thereto through inclinedports 14 in the ported partition. The rotary motor member is keyed to ashaft 15 by a key 16 and is tightened against a shoulder 17 by a nut 18on the screw-threaded end 19 of said shaft, said screw-threaded end alsoforming the means of attaching the tool to be driven. Said shaft isjournaled within the inner cylinder 3 and a removable bushing 20 ispreferably provided, which may be secured in any suitable way; but isshown as screwthreaded at 21 to the inner cylinder, crossslots 22 in theforward end being provided for the engagement of a tool to screw it inplace. A thrust plate 23 is seated against the cross-partition 4 and aflange 21 on the shaft extends between said plate and the rear end ofthe bushing 20.

An inlet passage 25 through the crosspartition and thrust plate in linewith a longitudinal passage 26 in the shaft admits the motive agent tothe thrust bearing and to the journal bearing through cross passages 27and discharges through the cross passage 28, thus affording a constantflow of the motive agent for lubrication; and as an additional aid forthis purpose an annular chamber 29 is formed between the shaft andbushing.

The supply head is screw-threaded at 30 for the attachment of a supplyconduit and a removable strainer 31 soldered to a ring 32 havingscrew-threads of like pitch with the threads 30 is seated against ashoulder 33 in the head.

Some modifications shown in Fig. 4 will now be described. Ananti-friction thrust bearing is interposed between the thrust plate 23and shaft flange 24, said bearing being shown as comprising two rings8-1 each having oppositely disposed hemispherical recesses openingthrough the outer walls so that when the rings are riveted together byrivets 35 with balls 86 in the recesses, the balls will proiect slightlybeyond the outside wall of said rings and contact with the thrust plate23 and the shaft flange 2%. Another modification consists in omittingthe lubrication passages through the shaft and providing the bushingwith a channel 37 and the shaft 15 with a recess 38. The motive agent isadmitted by a passage 25 through the cross-partition l and thrust plate23* to the anti-friction bearing and passes around the shaft flange 24-,into the channel 37 and is discharged in front of the bearing, themotive agent in its passage being more thoroughly distributed by therecess 38 in the shaft. A further modification is shown in that therotary motor member 11 is provided with a shroud 39.

Having thus described my invention I claim:
